Natural monument Zrubárka. In the Jablonec part of the Little Carpathians we can also meet surface karst in the form of holes and karst pits. The underground karst is represented by smaller holes and springs. A typical spring is a spring in the valley between the reservoir and the quarry, which was declared a natural monument under the name Zrubárka. Vyvieračka is one of the last in the mountains to be preserved in its natural state. A part of this protected area is also a complex of peat alder and wet meadows with an area of 3 hectares.
